SAO PAULO (AP) -- Brazil won't be at full strength for its first tuneup for the World Cup.

Coach Luiz Felipe Scolari says three or four players may be rested for the match against Panama on Tuesday because they are not in good physical condition yet.

Scolari did not name those who will not play. He said he will follow the recommendations from team doctors, who earlier this week put all players through a series of tests.

Scolari told reporters in Brazil's training camp in Rio de Janeiro that he hopes to have all of his players available for the match against Serbia on June 6, the team's last warm-up before the opener against Croatia six days later in Sao Paulo.
